Wakfu

Wakfu is a massively multiplayer online game (MMOG) which takes place in an original fantasy world. In the same spirit that animates its big brother, DOFUS, Wakfu will transport you to a magical universe full of sparkling humour. Whether you become a magus, a knight or a thief, you'll discover a heap of new character classes, a unique tactical combat system and strange, colourful landscapes.

Wakfu is intended for adventurers of all levels. It's up to you to find your own strategy and to succeed in the challenges you'll face along the way. Who knows, maybe you'll be one of Wakfu's greatest heros.
